"L'etat, c'est moi." Louis XIV.
"French King Louis XIV believed that he had the right to do whatever he desired as the ruler of France. When asked to explain how he thought the king should interact with the rest of the government and the people, his reply was, “L’etat, c’est moi”, or “I am the state”, meaning that he was bound by no rules and had no limits.
Over the years, the expression became a catch phrase for those government officials who overstepped their bounds."
